Application Scenarios & Design Considerations

32 MBIT (2MB X16, BOOT BLOCK) 3V SUPPLY FLASH MEMORY

Alternative Part Number

  • S29GL032N90TFI010 --: 32 Mbit parallel NOR flash in TSOP-48 with 90 ns access time, functionally equivalent to the M28W320CT and widely available as a drop-in replacement.
  • AM29LV320DB-90EI --: 32 Mbit 3V NOR flash with 90 ns speed grade and compatible x16 organization, a well-established alternative for legacy ST M28W designs.
  • MX29LV320EBTI-90G --: 32 Mbit low-voltage parallel NOR flash, 90 ns, TSOP-48 package, pin-compatible with the M28W320CT and suitable as a cost-effective second source.
  • AM29LV320DT-90EI --: 32 Mbit 3V boot-sector flash in TSOP-48 with 90 ns access, functionally compatible with the M28W320CT and widely available as a second source.
